Device to Remove Automobile Bodies 

 Without Scratching Them 



TWO men can remove a highly-polished 

 automobile body from its chassis 

 without giving its surface a scratch, by 

 means of the device shown in the accom- 

 panying illustration. 



This new device is attached to an over- 

 head trolley. It con- 

 sists of two sets of ^Hum 

 compass-like arms 

 pivoted to the ends of 

 a common cross- 

 member at the top. 

 The arms of each 

 set may be spread 

 out to reach the 

 front and rear ends 

 of the body in 

 exactly the 

 same manner 

 as a compass is 

 opened by

means of a rack and quadrant device. 

 Each of the arms is made with a telescop- 

 ing bottom for adjustment to the various 

 types of bodies. Loose collars with two 

 projecting arms are slipped over the bottom 

 of each arm to reach underneath the side of 

 the body and support it at unpolished 

 points. The looseness of the collars 

 enables them to be turned in any direc- 

 tion or moved up or down to obtain the 

 proper point of support. 



In operation, the framework carry- 

 ing the lifting device is moved along 

 its trolley so that the compass arms 

 are on each side of the body to be 

 lifted off the chassis. The arms are 

 then spread out and the lifting collars 



levers. It is then moved horizontally to 

 its point of deposit. The reverse of this 

 operation puts the body back on the 

 chassis. 



Sometimes the body must be lifted clear 

 off the chassis frame for a height of two or 

 three inches before the projecting arms on 

 the lifting collars can be placed on some 

 unpolished part. This may be accom- 

 plished by 

 means of a two- 

 part bar with 

 beveled ends, 

 which bar is 

 held together 

 at the center 

 by means of a 

 collar or sleeve. 

 By removing 

 the floor- 

 boards of the 

 car body, the 

 beveled ends of 

 the bar may 

 be inserted 

 between the 

 bottom of the 

 body sill and 

 the frame.

An Automatic Revolver No Bigger 

 Than Your Watch 



AUTOMATIC revolvers are made about 

 l\ as big as a standard watch. 



Little as these revolvers are, they never- 

 theless contain an automatic reloading 

 mechanism as complete as that of any of 

 their bigger brothers. They are "seven- 

 shooters." Six cartridges are held in the 

 magazines in the handle, and one in the 

 firing chamber. The pressing of the trigger 

 sends the firing-pin against a tiny percussion 

 cap. The bullets are one-tenth
